The AK-47 is my favorite gun in the game, hands down. It does appear to have a lot of recoil, but intentionally or not, the recoil is timed to reset the level of the gun between shots so your bullets still go where you originally aimed. It has a crapload of power, and I just like the gun in general including looks. I obviously can't start out with FMJ, so I use Red Dot Sight until I unlock FMJ, then I use FMJ until I unlock extended magazines. You may think Extended Magazines are kind of noobish, and while I agree to the extent in a spray-and-pray situation, I take careful aim with my shots and rarely find myself going full auto for more than a few seconds, I just like the peace of mind of knowing I don't have to reload as frequently if I get in a tight spot.

The AT-4 and RPG-7 have pro's and cons that lead to me switching off between them. The AT-4 is damned accurate, I can put it through windows across the map, but you only get one, and I've found it has less damage though I don't know if that's true or not. The RPG-7 comes with 2 rockets, allowing an extra use, but are a lot less accurate. It depends on how big the maps are which one I use.

Using flashbang allows me to not only clear rooms more effectively, but is very useful for situations where I need to get through a claymore without setting it off and alerting the enemy to my presence. Now the flashbang does make some noise but hopefully I can get away before he notices, and by doing this I don't have to worry about getting caught on obstacles and taking damage from the claymore.
I like C4 because it allows me to set traps and has a bigger blast radius than claymores do, and has a 360 degree blast, but you do have to be alive to trigger it. I use sound to know when to set it off, so I don't have to actually watch the doorway or wherever I throw it. Claymores allow me to do one of two things. I can use it as an advanced warning system to find out where someone is, or I can use it to block access to a certain area, both have ups and downs.

I don't use Marathon Pro for the ability to run forever, I use it for the increased hurdle speed. I honestly couldn't care less how long I can sprint as I don't usually find myself trying to cross the entire map at once, but the ability to climb up/over objects has saved my life more times than I can count. Lightweight is pretty much a necessity in my playing style in my opinion. I pick a location, stop for 1-2 kills, sprint to somewhere else, rinse, and repeat. Lightweight allows me to minimize the time between switching locations which reduces my chance of dying. The pro of it is helpful if I get caught sprinting, but I rarely have to make use of it. I do have a copy of this class with Cold Blooded Pro on it for instances where I find the need to be sneaky, or if the opposing team gets one of the higher kill streaks so I can run around without worrying about it. Now for ninja pro. For me this perk is make or break, I don't want some camper with a heartbeat monitor finding me, but the pro is even more useful...I can sneak up on people undetected even while sprinting, I can climb up ladders noiselessly, and it allows me to hear enemies footsteps more easily since I don't have the noise from mine getting in the way.

I do use painkiller which I sometimes catch flak for, but copycat is essentially useless for me, and I am morally opposed to martyrdom like I was in Call of Duty 4. Final Stand can be good, but the few times I've tried it out and actually managed to get a 4 death streak (not easy for me at all....I don't let myself get spawn trapped), it didn't turn out to help. Painkiller has helped me whenever I end up activating it, and when I don't it doesn't matter.

Anyway, this is my class of choice, of course, since I prestige after a few hours of being 70 I rarely have this class for long....thank god I'm 9th prestige now so soon I'll be able to use it exclusively.

I used to use a very similar class, but with a silenced scar, but this class is ridiculous amounts better. The tar has a higher rate of fire, a larger clip, a higher starting ammo count, and the same damage as the scar.

I've only started using this class today, but I can forsee this becoming my favorite, and most used class in no time. I can't believe I never thought of silencing the tar until today.

i hate the danger close noob tube combo... and then i started using it for headquarters games...omg

Tar-21 w/ noob tube
RPG- i always thought it was crappy, until i realized the potential for headquarters
C4
scavenger pro- infinite c4s to light up an entire building (4ks have never been so hilarious)
danger close pro- get ready for the post lobby swearing
sit rep- i just plain hate claymores, stopping TI in headquarters is helpful too

First of all, All Options with () are if I have bling on. I don't really care about death streaks (never really die three times in a row without a kill enough to need it) so I just leave it as Copy cat. The TAR-21 Is basically a SCAR-H with a larger clip and less recoil, FMJ is so I can shoot through walls at you. And yes, I will kill you if I see you run behind something. The F2000 has really bad recoil, but is powerful and shoots fast, and isn't bad when shot in bursts. Not to mention that you don't really need a secondary with it's amazing hip fire accuracy.

M9's and D'eagle Akimbo are 2-3 hit kills, which isn't hard when you're shooting over 15 SPS. I prefer M9's because it's easier overall to get akimbo, let alone actually kill with only one of the guns. We all know the horrible recoil with the D'eagle, makes me sick... sorta.

I'm shocked that no thermal snipers here have discovered the value of smoke grenades.
You know that you can see through those suckers with thermal, right? And if you have cold blooded you're invisible to everyone else.

This is the best versatility class set up I use. It is not specific to one game type or any one particular map. It is easy to take out cross map snipers, I can move in and clear out a building, I can hold down a flag, building, HQ, and in general be a BIG nuisance to the other team.
I do not use this set up for CTF or Wasteland.
This was my first post....peace

I dont really use any other classes, & i despise the noob tube. + these work against most people, although, theyre petty easy to counter in mai opinion, so, i dont see why they always get me lotsa kills.

I cant remember if kill streaks were asked for, but, ill put mine up. For nuke, its harriers, ac130(i hate chopper gunner, they get shot down whenever i call them in), & nuke. But, since i finally got the nuke stuff, im working to finishing the specter IV challenge.

When I prestiged my first time I was looking for a class that could get me through to my next 70 fast and I started messing around with runner classes. What I found was a very nice runner class for FFA that got me from 1-40 in only 12 hours of play time. Everyone I've told of the class likes it just as much as I do, in the fact that if used correctly, you can go 30 kills and 6 deaths on average per match.

The nice thing about this class set up is it's not hard to get used to. You always have the UMP45 upon prestiging and it's a quick boost up every prestige. I recommend you only leave this for FFA unless you find a viable set up for team-based multiplayer that you're happy with.

Noting on the Rapid Fire, only use this with the Steady Aim Pro. The UMP is a high recoil SMG that doesn't do well with the Rapid Fire, unless hip-firing, which then turns it into a VERY lethal thing to have sticking in your face coming around the corner.
The Holographic Sight is best to have with Commando Pro only in the fact that you're going to be in your sights most of the time unless running around. The Commando Pro will give you the edge on the enemy if they manage to get close enough to you.

The reason why I chose the killstreaks for Holographic UMP45 and the Silenced PP2000 is based off the fact that you're going to focus on 4 kills with the PP2000 going unnoticed and then upon getting your Counter-UAV, you can go crazy with your UMP and not be noticed on the radar.

The Holographic(Rapid Fire) UMP45 and the Akimo Ranger setup is just an assumption that upon using it you're not going to be very stealthy, so you're going to want to get the UAV so you can come to them and get a Care Package and maybe even a Harrier.

I hope that you find this class helpful, and I hope to see you raining hell-fire with it in FFA on the 360! :D

By far the most dangerous class I've used. TAR is the best gun in the game until you get to sniper distance. The recoil is negligible if you have skill. Smoke let's you close on snipers. Class is completely invisible. SoH gives you a huge advantage in face to face battles and you don't get caught reloading. If you run out in a firefight the M9 is there in a pinch. If you here someone around a corner you can go for a quick tac knife without exposing yourself afterward.
